BAG HOLDER AND OPENER.

Specification of Letters Patent.

Patented Nov. 21, 1916.

To all whom it may concern:

Be it known that I, HIYozo KAWATE, a subject of the Emperor of Japan,and resident of Seattle, King county,'lVashington, have invented certainnew and useful Improvements in Bag Holders and Openers, of which thefollowing is a specification.

My invention relates to paper bag holders and openers, and consists ofcertain novel constructions and combinations of parts which will behereinafter described and particularly pointed out in the claims.

The object of my invention is to provide a device which is cheap in costand which may be conveniently and quickly filled with a bundle of bagswhich are held thereby until wanted for use and which will cause theopening of the bag when it is withdrawn from the pile.

In the accompanying drawing I have shown my invention in the form whichis now preferred by me.

Figure 1 is a face view, Fig. 2 an edge view, and Fig. 3 an end view ofthe device in its empty or closed position. Fig. 4 is an edge view ofthe device distended for the insertion of sacks. Fig. 5 is a detailshowing a type of catch which may be used. Fig. 6 is a view of one endof the device with a few sacks in place illustrating the operation ofthe device. Fig. 7 is a top view, and Fig. 8 a side view of a modifiedconstruction with a number of sacks in place.

My invention is based upon the utilization of a helically coiled springor springs as the bag holding agency. The bottom edges of the bag areinserted between the coils of the spring while the latter is distended,and they are then yieldingly held between the coils when the springcontracts.

The common square bottom paper bag as it is received by the trade, isfolded so that the bottom lies alongside the body. It is so made thatone side, at its mouth, is slightly longer than the other, the shortside being that one which connects directly with that edge of the bottomwhich is outermost when the bag is folded.

If a helically coiled spring, as 1, which has been coiled close, bedistended, it makes an opening between each coil, which opening isadapted to receive the edge of a folded bag, and it will hold the bagsecurely if it is allowed to collapse or retract while the bag isbetweenthe coils. It is possible to quickly place a large number of bags inthis way. If a bag, so held, is engaged by the mouth end of the sidewhich is not held between the coils of the spring and pulled, itwillfirst be opened, as shown in Figs. 6 and 8, and then be withdrawn. It isthus in condition for receiving the goods which are to be placedtllGIElIlh The whole oper' atlon is natural, quickly done and theopening is automatic.

The device as shown in Figs. 1 to 6 has a main frame board 2 and twobars 8 sliding in guides which are shown as holes bored in the board 2.At one end of the frame is a lateral arm or board 20 to which one end ofsprings 1 is secured and at the other end is a hanger plate 21. Theouter ends of rods or bars 3 are connected by an off-set cross bar 30,to which the other ends of the spring are connected. The springs lieclose to the surface of the board 2.

The board 2 may be provided with catches for retaining the rods 3 whendrawn out and while the bags are being placed therein. The catchesherein shown consist of levers 4t pivoted at 41 and having a pin 12connected thereto and lying in a lateral bore which intersects the boreor guideway 00' copied by the rod 3. These rods 3 may be provided withnotches or apertures in which the pins 42 may engage, but as hereinshown, the pins engage the inner ends of the rods, and thereby preventretraction of the springs 1. The pins 12 are pressed inward by springs10, to engage the rods 30.

In the modified construction shown in Figs. 7 and 8, pairs of links orcrank arms 6 are connected by cross bars 5, and are pivoted at 60 toframe bars 7. The springs 1 are shown as connected to the cross bars 5.Without any bags in place, the parts would assume the position shown inthese figures by dotted lines. To insert the bags, the arms 6 are turnedaway from each other to distend the springs as is shown in dotand-dashlines. The device may be suspended, as by cords 70, in any convenientplace.

What I claim as my invention and desire to secure by Letters Patent is:

1. A bag holder and opener comprising a frame, a helically coiled springsupported thereon, means for distending the spring to insert the bagends between the coils thereof, and automatically-engaging means forholding said sprlng distended.

2. A bag holder and opener comprising a springs connecting said bars,and means for supporting said bars to permit their movement toward andfrom each other, said means limiting their inorement toward each other.

4i. A bag holder and opener comprising a frame board having guidingholes bored therein, bars slidable therein and connected to movetogether, helically coiled springs secured at one end to saidbars and attheir other end tosaid frame board, and automatically engaging means forholding said spring in distended position.

5. A bag holder and opener comprising a frame board having guiding holesbored therein, bars slidable therein and connected to move together, andhelically coiled springs secured at one end to said bars, at their otherend tosaid: frame board, and spring-pressed catches adapted to hold saidsprings in distended position.
